Infiniti Q30 Concept might be the cleverest Q model yet

When we first got official word of the Infiniti Q30 Concept, the Japanese automaker said that the crossover's "harmonious contrasts and dissymmetric philosophy" would "make an emotional connection with customers spontaneously." Now, we might not be heads of design studios or directors of marketing departments, but we're pretty sure we can translate that to: "The production Q30 will compete with the Audi A3 and Mercedes-Benz CLA-Class."
In all seriousness (if we can say that of a concept car painted a sort of rose metallic), the Q30 concept looks fetching here in Frankfurt; its rather convoluted and flowing bodywork just carried off successfully because of its grownup hatchback proportions and, frankly, huge wheels. The Q30 could seemingly slot into the current, attractive Infiniti range of production cars and not look amiss (though we'd prefer a color palette that looks a little less like Grandma's sitting room sofa).

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.

2014 Infiniti Q50 and Q60 Coupe and Convertible order guides leaked

The pricing and configurator for the 2014 Infiniti Q50 were revealed a couple months ago, and now InfinitiQ50.org has uncovered leaked order guides for Infiniti's all-new luxury sedan as well as the renamed Q60 Coupe and Convertible.
From the looks of things, if you'd like a rear-wheel drive Q50, you may have to have to special order it. All three Q50 RWD models say "Sold Order Only" on the model, mix and MSRP page. As for the Q60 models, the only differences for the 2014 model year - aside for the new name, of course - are related to exterior coloring. A new Venetian Ruby hue is being added to the palette.
